TreeON: Reconstructing 3D Tree Point Clouds from Orthophotos and Heightmaps
Computer Graphics Forum, EarlyView.Abstract We present TreeON, a novel neural‐based framework for reconstructing detailed 3D tree point clouds from sparse top‐down geodata, using only a single orthophoto and its corresponding Digital Surface Model (DSM). Our method introduces a new training supervision strategy that combines both geometric supervision and a differentiable shadow and ...

Contouring Signed Distance Fields by Approximating Gradients
Computer Graphics Forum, EarlyView.Abstract Signed distance fields are often represented by discrete samples (e.g., on a grid). Recovering the contour implicitly represented by the distance samples requires an approximation algorithm. Several recent approaches have shown that exploiting the information carried in each distance sample by explicitly constructing a surface point gives ...

How to determine spiral bevel gear tooth geometry for finite element analysis [PDF]
An analytical method was developed to determine gear tooth surface coordinates of face milled spiral bevel gears. The method combines the basic gear design parameters with the kinematical aspects for spiral bevel gear manufacturing.
